Water cooling attachment



Patented Mar. l6, 1937 v UNITED STATES PATENT OFFICE" 1 Claim.

This invention appertains to new and 'useful improvements in'the generalart of refrigeration and more particularly to a water or liquid cool- Iing' attachment for refrigerators.

The principal object of the present invention is to provide means forinstallation in mechanical refrigerators, ice boxes and other forms ofrefrigerators whereby water and other liquid can be cooled thoroughlywithout requiring but a very small space in the refrigerator. Anotherimportant object of the invention isto provide a liquid cooling featurefor refrigerators which will not depart from the conventional appearanceof the refrigerator.

1 These and other very important objects and advantages of the inventionwill become apparent to the reader of the following specification.

In the drawings: Figure 1 represents a fragmentary front ele- 20vational view of a refrigerator showing the dispensing faucet.

v Figure 2 is-a vertical sectional view taken substantially on the line2-2 of Figure 1.

Figure 3 is a fragmentary vertical sectional 25 view taken substantiallyon line 3-3 of Figure 2.

Figure 4 represents a fragmentary detailed sectional view takensubstantially on line 4-4 of Figure 3.

Referring to the drawings wherein like numeral: designate like parts, itcan be seen in Figure 2, that numeral 5 generally refers to aconventional refrigerator (preferably of the electric or mechanicaltype) which includesthe front wall 6, top wall I and side walls 8 aswell as the bot- 35 tom wall land back wall l0. Numeral ll representsthe refrigerating compartment and against the inner side of one sidewall 8 is disposed the flat coiled pipe l2 defining the water coolingcoils generally referred to by numeral ii. A suitable 40 frame It issecured to the inner side of the wall 8 and straps II are secured tothis frame and disposed across the convolutions of the coil it so as toretain the same firmly in'place. Numeral I! represents the inlet pipewhich extends throushthesidewallltoconnecttothecoil I:

at one end and while numeral It represents the outlet pipe which extendsdownwardly and as at l'I through the back wall of the alcove l8. To theouter end of this pipe ill the faucet I9 is secured in the usual mannerso that it overlies the 6 floor. 20 of the alcove IS in which is locateda small depression 2| from which the drain pipe 22 extends to passdownwardly through the bottom 9 and out through the rear wall III to anysuitable take-oif point. A glass orother receptacle 10- 23 canbe .placedon the floor 20 of the alcove It in a position underlying the faucet".

The usual water supply line 24 is connected to l the inlet pipeli' byway of the valve 25 and if desired beer or other liquid can be runthrough an adjacent pipe 28 by way of the valve 21 to the intake pipe I!when the valve 25 is closed.

A guard plate (see Figure 3) denoted by numeral 28 is placed against thecoil l3 and suitably secured to the straps l5 and frame ll. Thus thecoil is protected from damage. v

As can be seen in Figure 4, the guard plate 28 is secured to the strapsi5, and this may be by spot-welding or any other conventional method ormeans. The guard plate bears against the flat coil l2, so that any forceor pressure exerted by the ice shifting in the ice compartment will vbetaken up by the plate, thus preventing damage to the coil.

While the foregoing specification sets forth the 30 invention inspecific terms, it is to be understood that numerous changes in theshape, size and materials may be resorted to without departing from thespirit or scope of the invention as claimed hereinafter.

Having thus described the invention, what is claimed as new is:

Ina refrigerator, aflat coiled water tube disposed against the innerside of one side wall thereof, a supporting frame for the coil, and avertically disposed guard plate secured to the said frame between whichand the adjacent wall of the refrigerator the said coil is located.
